Our Verdict
Sony A80K/A80CK OLED
Sony X90K/X90CK
The Sony A80K/A80CK OLED and the Sony X90K/X90CK are different types of TVs, each with strengths and weaknesses. The A80K is better for dark-room viewing as it delivers deeper blacks, and it's also the better choice for wide seating arrangements because it offers a wider viewing angle. If you prefer something for bright-room viewing, the X90K gets much brighter to counteract glare.
